If it's the stuff in 16-round paper packets, I've used it before in my CZ-52 without any complaints. The only problems I've ever had from surplus 7.62x25 ammo was misfires, the worst being Czech stuff on 8-round stripper clips (3-5 misfires per magazine).
The best ammo, next to S&B or Norinco commercial, is 80's manufacture Romanian, but it seems to have dried up.
